Description

It would be helpful if sstabledump included tombstone expiration time in deletion_info output by calculating local_delete_time + gc_grace_seconds. To do this it would need access to the table schema to get at gc_grace_seconds which is currently not possible until CASSANDRA-9587.

Example output, assuming gc_grace_seconds is 86400 (10 days):

{ "name" : "data", "deletion_info" : { "marked_deleted" : "2016-07-01T18:00:06.800550Z", "local_delete_time" : "2016-07-01T18:00:06Z", "expires_at": "2016-07-11T18:00:06Z" } }
